HUNTC-077 I practiced sex with my super convenient new graduate sister who loses her memory when she gets drunk! I’m super lucky because I don’t remember her cumming inside me!

My little sister came to Tokyo for a job and asked me to let her stay with me for a week. She saw me enjoying a drink after the bath and said arrogantly, “What about mine? I’m old enough to drink now!” But after just a few drinks she was completely drunk! Just when I thought she was making fun of my virginity, she mistook me for her boyfriend and begged me for sex! She couldn’t help but ejaculate a lot into my sister’s pussy and knocked me out in seconds! The next day, my little sister had no memory of it, despite my awkward feelings. So… it’s okay to have sex every day!
